Catalytic Deoxygenation Chemistry

Selective production of aromatic hydrocarbons from lignocellulosic biomass via catalytic fast-hydropyrolysis using W2C/γ-Al2O3

“…Carlson et al demonstrated the conversion of small molecule oxygenates from glucose to aromatic hydrocarbons, CO, CO 2 and water using ZSM-5 catalyst in a Pyroprobe® in the absence of hydrogen [26]. The mechanism of conversion of oxygenates to a range of aromatics includes a series of decarbonylation/decarboxylation, dehydration, oligomerization, hydrogen transfer, cyclization, and isomerization reactions [26][27][28]. Compared to the CFHP experiment with γ-Al 2 O 3 catalyst, the linear/cyclic alkenes are significantly reduced with W 2 C/γ-Al 2 O 3 catalyst.…”

Highly stable amorphous silica-alumina catalysts for continuous bio-derived mesitylene production under solvent-free conditions

“…The C-C coupling reaction of alkanones via robust acid/base-catalyzed condensation is an efficient way to achieve deoxygenated aromatics from existing biorefinery streams, e.g., acetone from ABE-fermentation, in a single-step reaction without further need for metal-catalyzed dehydrogenation or upgrading via deoxygenation with hydrogen. [8][9][10][11] Furthermore, gas-phase fermentation by autotrophic acetogens offers a highly promising carbon-negative route to acetone. 12 Therefore, the efficient utilization of acetone via self-condensation for the formation of the aromatic product mesitylene (1,3,5-trimethylbenzene) is the focus of this study.…”
